Eh. Bad choice of words I guess. The implication is that the BSA and LDS were tight. Apparently to the point that 1 in every 5 scout was also a Mormon. Which is weird when Mormons account for only about 2 percent of the population at large.
I think that's in large part because Scouting was almost obligatory for LDS kids (it isn't any longer, since the LDS church cut ties with the BSA) --- nobody pressured us Catholic school kids to join the Boy Scouts, and most didn't. The troop, meanwhile, met in the basement of my local parish. What I'd just want to call out is that even in the 1980s, the Boy Scouts were openly and emphatically multi-faith. Not just ecumenical, but also going out of its way to teach Scouts that they were going to encounter other Scouts from totally different faith traditions.
The BSA may have been problematic for other reasons! I haven't thought that much about them since I dropped out (I only made it to Scout First Class). It was a sort of inherently conservative organization, as you'd expect just from hearing the Scout Oath. You can see where the Scouting ethos would mesh pretty perfectly with LDS culture.
